Effects of the incorporation of biosolids on soil quality: temporal evolution in a degraded inceptisol (typic endoaquepts)
The purpose of this study was to determine the temporal evolution of soil properties following the incorporation of biosolids in a degraded Inceptisol soil (Typic Endoaquepts). The study was conducted in the Araucanía Region of Chile, where two sampling zones were established: a control zone without...
